As a starting point, you can check Mac2Sell, eBay (including completed sales), or Amazon for prices of similar models, to get an idea of what a reasonable price may be. Then adjust the price to account for condition, configuration, remaining AppleCare coverage (if any), etc.

The system is in perfect condition still has 8 months AppleCare. Are u talking 400 in American $? Because I was actually thinking at a guess myself that it would be worth £280. I had a quick look on eBay and couldn't really see any on the uk version.
